So, a couple of errors in cards have been discovered since I first made the set available. A couple more just in the last few days. I have made an errata page to compile any changes in 4eXtended cards. However, due to its nature, all cards for download will be updated when the errata is made and the card spoiler should be update-able as well. So this is primarily for people who have printed out cards previously and want to make sure no changes have been made since then.
